Inside your digital life

Everyday Technology3D printing, layers, slicing and material paths

How can a moving nozzle build a solid object?

Turn a miniature stand, slice its real geometry and watch material paths build it. Solve a support puzzle, inspect actual fracture images, and take your design and learning notebook home.

Everyday TechnologyAnimation, stop motion, frames and timing

How do still pictures become a moving animation?

Direct a rigged fox, capture poses and build a real animation. Change pauses, compare in-betweens, inspect a historic motion study, and save your own film.

Everyday TechnologyTouchscreens, capacitive sensors and resistive screens

How do touchscreens detect your fingers?

Open a phone into its sensing layers. Move virtual touches, decode changed readings, solve a two-finger mystery and discover why different screens respond to different objects.

Computers, Networks & AIImage compression, PNG, JPEG, lossless and lossy files

How do image compression, PNG and JPEG work?

Tell a decoder what to do, paint a tiny picture, make a real PNG and count every byte. Compare reversible prediction with discarded color detail and actual JPEG evidence.

Everyday TechnologyCamera exposure, shutter speed, focus and rolling shutter

Why is my moving photo blurry?

Photograph a moving toy, shorten the exposure, and unroll the time behind each row. Compare motion blur, rolling shutter, missed focus and low-light noise using your own saved captures.

Computers, Networks & AIRecommendation algorithms, social feeds, content-based filtering and feedback loops

Why does an app keep showing me more of the same?

Open two pretend feeds. Watch a card, change a rule, and pull out the receipt for the next recommendation. Discover a feedback loop without handing over any real viewing history.

Computers, Networks & AIEncryption, end-to-end messages, VPNs and cryptographic keys

Who can read a message as it travels online?

Send a fictional note, become a network observer, and open the layers for which you have a key. Compare protected connections, end-to-end encryption and a VPN using real browser cryptography.

Computers, Networks & AIVideo game graphics, 3D rendering and pixels

How does a flat screen create a 3D game world?

Drive an original little rover behind an arch, turn the camera, and open one pixel of the actual picture. Discover which triangle wins, where its color comes from, and what changes when you add more samples.

Computers, Networks & AIWi-Fi, wireless signals, game lag and latency

Why does my game lag in this room?

Press jump on an original game, open the room around it, and discover where a reply spends its time. Share the radio with a tablet, inspect tiny waiting intervals, and compare a teaching signal model with real laboratory evidence.

Computers, Networks & AIPhishing, fake messages and account security

How can a fake message put an account at risk?

Peel a familiar-looking message away from its destination. Take apart real URL structure, compare passwords, codes and passkeys, and discover why checking through a known route changes the evidence.

Computers, Networks & AIThe internet and data packets

How does a message find its way across the internet?

Send “SMALL IDEAS!” through a network. Delay a piece, lose another, and watch what the receiver can actually use.

Computers, Networks & AIBinary numbers and logic gates

How do zeros and ones become a calculation?

Flip real input bits on a little calculator. Build a result from simple rules, and follow a carry as it crosses four columns.

Computers, Networks & AICPUs and computer instructions

How does a CPU turn instructions into results?

Write a tiny real assembly program, watch values move through a processor’s logical parts, and stop at the instant an answer becomes stored state.

Computers, Networks & AIMachine learning and training

Can a machine learn the wrong pattern?

Train a real classifier on editable inspection cards. Reveal a confident mistake, repair a misleading shortcut, and freeze your model before opening its reserved test.

Computers, Networks & AILanguage models and AI text

Where does a language model’s next token come from?

Open a genuinely trained miniature Transformer. Change token tiles, inspect real attention and vector calculations, sample a continuation, and test the limits of a confident prediction.
